Application filed December 4, 1913. Serial r10. 894,632.

To all whom it may concern:

Be it known that I, IVAN Gr. CownLL, a citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented a new and useful Gas Floor-Furnace, of which the following is a specification.

lhis invention relates to gas heaters, which are adapted to be placed in the floor of a room in the manner of a floor register.

Ihe main object of the present invention is to provide convenient and effective means for lighting the heater.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate an embodiment of the invention, and referring thereto:

Figure 1 is a side elevation of a heater and my improved lighting means in connection therewith, the floor being shown in section. Fig. 2 is a plan of the heater. Fig. 3 is a section on line w m Fig. 7, with the register in open position. Fig. 4 is a view similar to Fig. 3 with the register in closed position. Fig. 5 is a detail section of the closure means for the ignition tube. Fig. 6 is a section on line as -m Fig. 7. Fig. 7 is a section on line w a Fig. 6.

My improved lighting device is adapted to be placed within a register heater 1, preferably in the form of a rectangular sheet metal box, having an outwardly extending flange 2 at its upper end adapted to rest on the floor beam 3 of a floor 1, as shown in Fig. 1, to support the heater. A top plate or frame 5 is secured to the top of the outer casing 1, and is provided with a central opening occupied by a register frame 6. A perforated register plate 8 is mounted over said register frame and register wings or shutters 9 are pivotally mounted at 9 on said register frame, the said wings being connected together by a bar 10, so as to move in unison to open or closed position, said bar being provided with a projection 10 extending upwardly through the register plate 8 into position for convenient operation.

A. gas burner 44 comprising a plurality of perforated radial arms within combustion chamber 34 is connected by nipple 4.5

at its center to a gas pipe 16 having a valve 47 whose stem 48 extends, to the top of the floor t in which the heater is placed and is provided with an operating key 50. An

igniting tube 51 is screwed into a boss 52 on a top plate 18 within the upper part of the heater, and extends up to the level of the register of the heater, said tube communicating at its lower end with an igniting tube 51 which extends downwardly within the heater, and is connected at its lower end to the center of a collector plate 53 which plate has a plurality of radial arms extending from its center, which arms are located directly over the radial arms of the gas burner Said collector plate 53 is preferably provided with arms extending over the several branches of burner 44, each arm of the collector plate being concave on its lower face, as shown at 53 for the purpose hereinafter set forth. A valve or closure member 55 is provided for the ignition tube, said valve being hinged to one of the wings 9 of the register so as to be pushed over the tube 51 when the register is opened.

The operation is as follows: When it is desired to light the heater the key 50 is operated to open the valve 47, causing combustible mixture to pass through the burner 4A and to be collected by plate 58 so that the ignition tube 51 becomes filled therewith. The register is closed, and the flap or valve 55 being drawn off of the ignition tube so as to open said tube, a match is applied to the upper end of the ignition tube 51, so as to ignite the mixture therein and the flame then back-fires down to the burner 44-, the gas burning thereafter in the usual manner. The register is opened causing the flag or valve 55 to be pushed over on top of the ignition tube after the ignition is completed, so as to close the same so that no fumes or heat will pass out into the room through said tube. The heat then passes through the heater into the room. The collector plates serve to retain a considerable amount of heat in the heater and keep the heater hot, whereby the heater is caused to operate most efficiently.

What I claim is:

1. In combination with a heater, a burner therein having gas outlets in its upper face only, and an ignition tube extending vertically above said burner from a point in proximity to the burner to a point near the top of the heater, said tube being provided at its lower end with mixture collecting means extending over said burner.

2. In combination with a heater, a burner therein, an ignition tube extending from a point a short distance directly above said burner, and a plate on thelower end of said tube resting directly over said burner.

3. In combination with a heater, a burner therein, an ignition tube extending from a point a short distance directly above said burner, a plate on the lower end of said tube resting directly over said burner, and the lower face of said plate being concave to collect the gas from the burner for ignition through said tube. 4. In combination with a heater, a burner therein, an ignition tube extending from a point a short distance directly above said burner, a plate on the lower end of said tube resting directly over said burner, the lower face of said plate being concave to collect the gas from the burner for ignition through said tube, and the concavity of said plate leading to the lower end of said tube so as to direct the gas thereinto.

5. In combination with a heater, a burner comprising a plurality of radial arms ex- Copies of this patent may be obtained for tending from a common center, a'plate having a plurality of radial arms corresponding to the burner arms and resting directly above said burner arms, and an ignition 7 tube extending through the center ofsaid tube extending from a point a short distance above said burner to a point directly below one of said shutters and a valve hinged to said last mentioned shutter so as to be f pushed over, the ignition tube when the shutter is open. v V

In testimony whereof, I have hereunto set my hand at Los'Angeles, California, this 28 day of November, 1913.
